摘要
通过航空摄影测量技术获取高分辨率的卫星影像和高精度的数字高程模型,制作较大比例的地形图弥补了传统航测因地域、空域等受限制的缺陷.以线路工程为例,采用 12.5 m分辨率遥感影像,举例说明如何利用高分辨率卫星影像数据生成三维立体大场景进行电力线路排位、优化及测制断面工作.此方法为线路工程项目开展可行性研究、初步设计及施工图定位提供了丰富而准确的数据资料.此外,对举例项目中GPS实地测量控制点进行了精度分析得出高分辨率卫星影像在输电线路工程应用有较好优势.
Abstract
Acquiring high-resolution satellite images and high-precision digital elevation models through aerial photogrammetry technology,and producing large-scale top maps,compensate for the limitations of traditional photogrammetry due to regional and airspace constraints.Taking the line project as an example,this paper uses 125 m resolution remote sensing images to illustrate how to use high-resolution satellite image data to generate three-dimensional large scenes for power line alignment,optimization,and section.This method provides rich and accurate data for the feasibility study,preliminary design,and construction drawing positioning of the line project.In addition,the accuracy analysis of field measurement control points in the example project shows that high-resolution satellite images have good advantages in power transmission line projects.
